抄録

A 62-year-old man was admitted because of detection of a tumor shadow on health screening chest X-ray films. Chest CT showed a tumor shadow in the right S2 and swollen mediastinal lymph nodes. The tumor was diagnosed pathologically as squamous cell carcinoma by TBLB, and right upper lobectomy with mediastinal lymph node dissection was performed under a diagnosis of primary lung cancer. Postoperative sections of the pulmonary nodular lesion showed an atypical growth of the neoplastic cells composed of a variety of histological features. The immunohistological stains were HCG (+), AFP (+), HPL (+), and CEA (+). The final pathological diagnosis of the tumor was germ cell tumor (choriocarcinoma, yolk sac tumor andembryonalcarcinoma). Since there were no abnormal findings in testes or other organs, the primary site of the malignant germ cell tumor was concluded to be the right lung. Despite postoperative chemoradiotherapy, the patient died 12 months postoperatively due to multiple pulmonary metastasis.
